# Calculator₊ vs Calculator

The clearest difference is ratings volume: Calculator₊ at 1.7M against Calculator's 147K. Calculator₊ also leads on chart position (#92 vs unranked) and review sentiment (63% vs 51%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Calculator₊ sells 12 in-app purchases, starting at $0.99 per month and Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Calculator₊ holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Calculator₊ has 1.7M ratings behind it against 147K, so its average is the more settled of the two. Written reviews point the same way: 63% of Calculator₊'s written reviews are positive against 51% of Calculator's.

Calculator₊ ships an update every 3 weeks, Calculator every 2 weeks. Both last shipped on November 1, 2026.
